CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of Korean Patent Application No.10-2016-0089604, filed on Jul. 15, 2016 in the Korean IntellectualProperty Office, which is incorporated herein by reference in itsentirety.

BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates to a cage apparatus for construction, andmore particularly, to a structure for connecting a cage for constructionwith a gondola for exterior finish work in order to carry out frame workand exterior finish work to be stacked up.

Background Art

In general, finishing work for an outer wall of a high-rise building iscarried out on a gondola when support beams are mounted on a rooftop andthe gondola is hung up after frame work is completed. Because suchexterior finish work before frame work is finished cannot be started,there is a process gap between the two works, and it may cause anincrease of the entire construction period of time.

Therefore, in some of construction sites in Korea, in order to carry outframe work and exterior finish work at the same time, a method of addinga work plate of one step or two steps below a cage for construction or amethod of additionally installing a cage for finishing work of an outerwall below a cage for frame work is adopted.

However, the method of adding the lower work plate has a limitation inadding the number of steps of work plates due to an increase of cageload and an increase of construction costs. Moreover, the method ofadding the lower work plate has additional disadvantage in that framework may be delayed and the entire construction period of time isincreased because it is impossible to raise the cage to an upper layerif the construction-per-layer periods of frame work and exterior finishwork are not synchronized.

The method of additionally installing a cage requires a lot of time toinstall and dismantle the additional cage and causes an increase ofconstruction costs. Particularly, the two methods to carry outconstruction work by the unit of a layer may cause waste of productivityand an increase of construction costs because workers for exteriorfinish work can secure just a work amount of one layer during theconstruction period per layer. Therefore, technology for minimizingadditional costs, allowing the workers for exterior finish work tosecure a sufficient work amount, and supporting concurrent constructionof frame work and exterior finish work is required.
